I usually go to Sam's Club in the morning; when they open at 7am.
That's the best time to buy Chuck Roasts that have been marked down...
as well as any other meat that has been marked down.

I will keep 2 or 3 in the freezer during the winter to make Pot Roast with
in the Crock pot. In the summer; I will either cook them whole on my
grill (can't have a smoker where I live); they can take 1 1/2 to 2 hours,
or I just cut it up in to 6 or 8oz. portions and grill them Hot & Fast.
Chuck Roasts have lots of flavor.

I'm sure you could easily smoke it; then shred it for sandwiches; if you
have a lot left over; you can freeze it and use it later for Burritos & Tacos,
or Chilie, or French Dip sandwiches....you can even toast a hamburger bun,
and warm up some of the Shredded Beef you made....pile a nice portion on
top of both the bun top & bottom that is laying on your plate face up.
Then spoon some homemade Chilie (or Green Chilie) on top of that,
followed by some, grated cheddar cheese, and you'll have a
fantastic meal to devour.
